Problems solved by technology

[0016] In practical applications, the above solution has the following problems: the utilization rate of air interface resources is low
[0017] The main reason for this situation is that when a UE may have multiple priority queues with different priorities at the same time, and the amount of data in these queues is less than the amount of data transmission that can actually be accommodated on the HS-DSCH in the current TTI, The MAC-hs entity can only transmit the data of one of the priority queues, so that the actual bandwidth of the current TTI on the HS-DSCH is not fully utilized, and the utilization rate of air interface resources is low.

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] In the present invention, the MAC-hs entity on the network side concatenates PDUs of at least two (or multiple) priority queues of the same UE to form a new concatenated PDU, the structure of which is shown in FIG. 5 . The format of each PDU in the concatenated PDU is the same as that of the prior art, the only difference is that the padding fields of each PDU are placed at the end of the concatenated PDU, and at the same time, the initial position of the padding field is increased. A fill pointer field, and a fill pointer flag (Pointer Flag, "PF" for short) indicating whether there is a fill pointer field.

[0057] When the UE's MAC-hs entity receives the concatenated PDUs, it processes the padding fields according to the PF and padding pointer fields, and...

Abstract

The invention discloses a transmission method and system for multiqueue grouping data. Wherein, transmitting PDU in multiple PRI queues in MAC-hs entity of one UE to the UE by means of cascade, while holding original format for every PDU; setting the fill field on end of cascade PDU, and generating corresponding fill pointer field when the fill field over 21bit.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to packet data transmission in mobile communication. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP"), as an important organization in the field of mobile communications, has promoted the standardization of the 3rd Generation Mobile Communications (The Third Generation, referred to as "3G") technology. Its early protocol Both uplink and downlink services in this version are carried on dedicated channels. [0003] With the development of mobile communication technology, 3G technology is also constantly evolving. High Speed ​​Downlink Packet Access (HSDPA for short) and High Speed ​​Uplink Packet Access (HSUPA for short) are important evolutions of 3G technology. Scheduling and retransmission of data packets in HSDPA and HSUPA are controlled by a base station node (Node B). [0004] Among them, HSDPA w...
